store string data in rrd database

is it possible to store string data in rrd database

for example ,

if i want to store

Employee Name 
Employee Address
Employee Phone
Employee Mac Addr

in rrd database using py-rrdtool , if it is possible开发者_如何转开发 then how to do that can any give me road map to that

rrdtool stores time series numerical data only, use sqlite or in python maybe even something simple like pickle to store your text data ... if the data is related to an rrd file, store it in a pickle with a different extension right next to the coresponding rrd file.
